Take the Faded Journal Page to Tavernkeep Smitts.
I know of someone who might be able to assist you. Back when I was leading the Stormwind Guard, we used to get drinks at the Scarlet Raven Tavern in Darkshire. The Innkeeper there, Smitts, was quite an expert on the local lore. Show him this page and see what he has to say about it.
